stainless steel

We stock a complete line of ANSI one strand 304-grade stainless sprockets both as A-Plate style and B-Hub style. We maintain these on the shelf as standard stock bores. Nevertheless, we are able to supply sprockets with completed bores because of our fast-reaction internal industrial machine store. Typically our sprockets are manufactured out of 304 quality stainless, but 316 in addition to a few other grades are chain sprocket available upon request.

double pitch

Black Ace Dual Pitch Roller Chain Sprockets are produced with the highest integrity. You will realize value, as these sprockets are flame-cut and machined with the best precision available on the market.

ANSI Standard Torch Profiles
A – B – C Hub Types
A Type (no hub) typically found in weld-on applications.
B Type (hub on one side) used in applications where clearance width is narrow. Less expensive than C Type.
C Type (hub upon both sides) found in applications where B Type isn’t wide enough to withstand torques made by drive.
Split Style Structure – Once you use a Split Sprocket, you may never want to use a setscrew mount style again. Removal or installation is a breeze. Can be used in practically all applications. Another advantage to Dark Ace’s split sprockets is chain sprocket definitely that the shaft/keyway security is much tighter than a typical setscrew mount.
Hardening Available – Flame hardening of sprockets is certainly available as a choice.


This 80SF30 sprocket is a durable, high quality, and precision sprocket with 30 hardened teeth that is manufactured to accept an SF bushing. A thing that is notable concerning this sprocket is certainly that it completely meets all ANSI Standards, which insures proper get in touch with between the #80 roller chain and sprocket. This also prevents premature wear or breakage and means that the sprocket will sprockets directly interchange with additional manufactures sprockets. This sprocket is also black oxide coated therefore increasing resistance to the environment and will prevent early corrosion. 80SF30 sprockets are manufactured to accept a SF type QD bushing which, we also stock with a wide range of bore sizes. Additionally offer sprockets with completed bore configurations, and if you need a custom sprocket we have the capabilities on offering them within an easy lead-time and at really great prices. To find out more or large inquiry demand please contact us and we will be happy to help you.

taper lock

Tapered Bushing Sprockets (TL) Bushing-Bore Sprockets for ANSI Roller Chain. Modify bore size without changing your sprocket.Easy to set up, Taper-Bushed Sprockets provide you with the flexibility to utilize the same chain sprocket sprocket with different shaft diameters. Purchase Taper-Bushings(Sold separately) to match the bore sizes you will need. Use with ANSI single and double-strand chain. These steel sprockets and bushings fulfill all ANSI requirements.

cast iron

he sprocket we manufacture is based on many years of design experience.
Ductile cast iron (FCD600) may be the standard material of sprockets for cast chain. If the application form requires, we also
manufacture sprockets with surface hardened tooth techniques for higher wear resistance.

engineering sprockets

Conveyor sprockets (mill sprockets, engineering course sprockets, engineered sprockets) are used in conjunction with conveyor chains or conveyor belts. They are toothed gears or profiled tires that mesh with a conveyor chain or belt to transmit rotary motion. Single, double, triple, quadruple and quintuple conveyor sprockets are commonly available.

conveyor sprockets

Conveyor sprockets (mill sprockets, engineering class sprockets, engineered sprockets) are found in conjunction with conveyor chains or conveyor belts. They are toothed gears or profiled wheels that mesh with a conveyor chain or belt to transmit rotary motion. Single, dual, triple, quadruple and quintuple conveyor sprockets are commonly available.
